The next generation of exoskeletons: lighter, cheaper devices are in the works

Many researchers and engineers are busy in their laboratories working on devices that will bring mobility to people who have lost function in the lower body due to an accident, stroke, multiple sclerosis, or other disorders. "Several pretty sophisticated exoskeletons are already on the market now, and they are all similar to each other in terms of technologies, but we're not ready to replace the wheelchair yet," said exoskeleton developer Homayoon Kaz Kazerooni, Ph.D., professor of mechanical engineering at the University of California (UC) at Berkeley. "Eventually, we will have devices that are used by individuals on a daily basis to replace wheelchairs but not with the existing technology. We're at the beginning of a much bigger era in exoskeletons."
